The stabilization effect (breast cancer data). Accuracy curves from the stepwise approach with different algorithms settings. In each curve, the right end corresponds to an accuracy from the expression data and the left end corresponds to an accuracy from the clinical data. The closer to the right end of the curve, the larger the differences in accuracy curves that are observed. This is not unexpected, because closer to the right end more and more samples are classified using the high dimensional expression data and vice versa.
